This is a weekly snapshot of what was happening in Dallas, the nation and the world the year President John F. Kennedy was assassinated.

Dallas: Mayor Earle Cabell tells the Dallas Transit Authority that the city will take over the privately held company if service does not improve. The DTA is feeling the heat over the chill on its buses during a recent cold snap and a report that the system carried 1.5 million fewer people in 1962 than during the prior year. Investor Harry Weinberg of Scranton, Pa., owned 70 percent of DTA stock.

Texas: The Air Force says it is resuming training flights of the B-58 Hustler, the first supersonic bomber. The Fort Worth-built plane had been grounded since a fall crash in Indiana. The B-58 introduced Texans to the sonic boom as it rattled windows and nerves during test flights across the state.

Nation: Thirteen months ahead of their heavyweight title bout, champion Sonny Liston and his 21-year-old challenger Cassius Clay — later Muhammad Ali — are already several rounds into trash talk. The champ wasn’t alone in misjudging the contender’s potential. The Associated Press report of the prizefighters’ meeting at the Philadelphia Sports Writers Association Banquet quoted Liston, but gave little credibility to “the loquacious and boastful Clay, who promised to kayo Liston in six.” Ali won the 1964 fight with a TKO in seven.

World: French President Charles de Gaulle scuttles Britain’s bid to join the eight-member Common Market, despite the Kennedy administration’s warning that the veto could imperil the NATO alliance.
